Luuna and Bailey spent 1-2 hours together at the rescue she came from, then they went into the same carrier (a new one) and came home. They had a few small scraps (which i split up), couple of minor scratch wounds which I cleaned up, but mainly just fur pulling and humping. I guess you don't know whether a quick bonding will work, but then slow bondings done by the owners don't always work either. Personally I would rather not leave my rabbits with someone else for 3-7 days, which tend to be the times I have seen recommended by different rescues.
